  Structures and magnetic studies of two new bimetallic chain complexes constructed by manganese(III)–(Schiff-base) and mer-tricyanidoferrate building block

  摘要：

  Two new cyano-bridged bimetallic complexes, {[Mn-III(5-CH3)salen][Fe-III(qcq)(CN)(3)]}(n)center dot 1.85H(2)O (1) [salen = N,N'-ethylenebis(salicylideneiminato) dianion; qcq = 8-(2-quinoline-2-carboxamido)quinoline anion] and {[Mn-III(acphen)][Fe-III(qcq)(CN)(3)]}(n)center dot 6.46H(2)O (2) (acphen = bis(o-hydroxyacetophenone) ethylenediiminate), have been synthesized and characterized both structurally and magnetically. The structures of 1 and 2 are both 1-D zigzag chains connected through pi center dot center dot center dot pi stacking and short contact interactions to form extended supramolecular networks. The magnetic measurements revealed the presence of antiferromagnetic Fe-III center dot center dot center dot Mn-III interactions in 1 and 2. Interestingly, weak slow magnetic relaxation was only detected for 1, indicating the intermolecular antiferromagnetic interactions in 2 are stronger than that in 1 and lead to the disappearance of the 1-D magnetic behavior.

  Four new Mn-III(Schiff base) and/or [Fe-III(L)(CN)3]- (L = mpzcq, qcq) based complexes, PPh4[Fe-III(mqzcq) (CN)(3)]center dot 4H(2)O (1), [Mn-III(5-CH3O-salen)(H2O)](2)[Fe-III(mqzcq)(CN)(3)](2))-2H(2)O (2), [Mn-III(5-CH3-salen)] [FeIII(mqzcq)(CN)3]}center dot H2O center dot-CH3CN (3) and [Mn-III(4-CH3O-salcy)] [Fe-III(qcq)(CN)(3)])center dot 2CH(3)CN (4) (mqzcq = 8-(5-methylpyrazine-2-carboxamido)quinoline; qcq = 8-(2-quinoline-2-carboxamido)quinoline; salen = N,N '-ethylenebis(salicylideneiminato) dianion; salcy = N,N '-(1,2-cyclohexanediylethylene)bis(salicylide-neiminate) were synthesized and characterized structurally and magnetically. The results reveal that 1 and 2 are discrete 0-D structures while 3 and 4 are 1-D zigzag neutral chains. Notably, the out-of-plane Mn-2 dimer, [Mn-III(5-CH3O-salen)(H2O)](2)(2+) and [Fe-III(mpzcq)(CN)(3)]- are both presented in 2 with the Mn-2 dimer being further organized into 1-D supramolecular chain arrangement via hydrogen bonds interactions. Magnetic investigation indicates that weak intradimer ferromagnetic coupling exists in 2 while dominant intrachain antiferromagnetic couplings in 3 and 4. Moreover, slow magnetic relaxations were also observed for 2 and 3. (C) 2014 Elsevier Ltd. All rights reserved.
